Send the smallest example that demonstrates the issue

Contact OnlineCalculator.xyz at support@onlinecalculator.xyz. The most useful message identifies one route, lists a neutral set of inputs, quotes the displayed output, states the expected output, and shows the calculation used to reach that expectation. A concise reproducible example lets the issue be tested without a name, account, school, employer, purchase history, or personal document.

The site is operated by OnlineCalculator.xyz, 30 N Gould St Ste R, Sheridan, WY 82801, USA. Email is the only public support channel. There is no chat widget, user dashboard, upload portal, telephone queue, or social sign-in. Email is not part of the local calculator; messages travel through mail services and are handled under the Privacy Policy.

Formula and behavior reports

If arithmetic appears wrong, include the exact mode and units. “Percentage result is wrong” is difficult to distinguish from a denominator misunderstanding. “On /tools/percentage-change-calculator, old 80 and new 100 display 20% but the shown formula gives (100−80)/80×100 = 25%” is reproducible.

For a fraction issue, provide all numerators, denominators, selected operation, reduced result, and expected result. For conversion, name both source and target units. For geometry, specify the selected shape and dimension labels. For a directory-match issue, provide the short non-sensitive phrase, selected filters, result order, and the route you expected to match.

Screenshots can help with focus, layout, or responsive problems. Crop browser tabs, bookmarks, notifications, and unrelated content. Typed inputs should be neutral. Never attach account statements, assignments containing another person’s information, identity documents, credentials, or proprietary datasets.

Content corrections

A correction message should quote the route and heading, identify the disputed statement, propose a precise replacement, and include a primary source or mathematical derivation when appropriate. Elementary formulas can often be verified directly. Claims about standards, unit definitions, accessibility, browser behavior, or law need an authoritative current source.

We distinguish a convention from a fact. A page may intentionally use a disclosed rounding mode or a 52-week normalization. A correction should explain whether the convention is inconsistently applied, incorrectly described, or simply different from another tool. Clear disagreements improve the editorial record.

Accessibility reports

Useful details include the route, task, browser, operating system, zoom level, keyboard sequence, and assistive technology if relevant. Report missing labels, confusing focus order, invisible focus, inaccessible error text, live results that are not announced, color-only meaning, clipping, or controls that cannot be reached.

There is no need to disclose a diagnosis. Describe the interaction barrier. A report such as “After activating Calculate with Enter, focus remains on the button and the new error is not announced in NVDA” gives a testable state.

Privacy and security requests

Privacy questions may concern hosting metadata, support correspondence, local fields, or browser storage. State the pathway and relevant jurisdiction. Because calculator entries are designed not to reach the operator, there is ordinarily no server-side calculation record to retrieve. An email itself is a record that may be located and handled according to applicable law and retention needs.

For a security concern, do not access data that is not yours, degrade service, evade controls, or publish an exploitable method before allowing reasonable investigation. Describe the affected public route, prerequisites, observed result, and a safe reproduction. The service does not offer or imply a paid bug-bounty program.

Proposing a focused calculator

A strong proposal contains a one-sentence unknown, named input roles, formula, defined result, worked example, undefined cases, and why an existing page does not cover the interaction. “Add every finance calculator” is outside scope. “Convert a finite geometric sequence from first term, ratio, and term count with a zero-term guard” is bounded enough to evaluate.

Submitting a suggestion does not guarantee publication, a response deadline, payment, ownership, or confidentiality. Do not send trade secrets or material you are not authorized to share. The operator may independently use general feedback unless a separate written agreement says otherwise.

What support cannot provide

Support does not complete assignments, certify answers, interpret regulated rules, choose significant figures for professional work, or advise on health, loans, investments, taxes, legal rights, engineering safety, or purchases. It cannot recover a calculation after reset because no cloud history exists. It cannot open an uploaded spreadsheet because uploads are not part of the service.

Messages may be prioritized by security, privacy deadlines, accessibility impact, widespread calculation defects, and reproducibility. No immediate response or specific resolution is promised. Promotional link requests, copied-content offers, fake testimonials, and requests for undisclosed ranking manipulation may be ignored.

A model report

Route: /tools/fraction-calculator. Operation: division. Input: 3/4 ÷ 2/5. Display: 6/20. Expected: 15/8 because 3/4 × 5/2 = 15/8. Browser: current Chrome on Windows. The substituted formula appears to multiply straight across without using the reciprocal.

The example contains every field needed to reproduce and diagnose the logic. It does not reveal a real student, class, or document.

Frequently asked questions

Can I send a spreadsheet for calculation?

No. The service has no upload analysis. Reduce the issue to a neutral bounded input set.

Where should accessibility feedback go?

Email support@onlinecalculator.xyz with “Accessibility” in the subject and include the route and interaction state.

Can support retrieve my last result?

No. Calculator values are not stored in a user history or account. Re-enter the values if you still have them.

May I suggest a new unit?

Yes. Name the unit family, authoritative definition, conversion factor or affine formula, symbol, range, and edge cases.

When the report contains one route and one reproducible neutral case, email it to support@onlinecalculator.xyz.
